well it sounds like you knocked a rod loose that connects
to the door latch. now you would have to take off door panel and fix this issue from the inside good luck.

replace IC of car door lock... this is a little black box inside the steering wheel cover

I would guess the problem would be located with the drivers door harness. All of these items are controlled from the same place, remove door panel and check harness connectors for tightness and water damage.

Those are all really common symptoms of the alternator going bad on those cars. I would have it checked to make sure it's charging properly.

It had all the symptoms of a low battery. Glad you got it figured out!

If you have trouble in fixing your vehicles, try this link. Very helpful

Check the mega fuse in the underhood fuse panel, picture below

This is a common problem, there is either a pinched wire in the harness that is in the door jam or your fuse block is shot, there is a gm service bulletin out on this, I would call your local dealership to find out if it is covered.
